However, in either a combined or a split out instances configuration,
the way you probably want to do this is by making the routers
conditional rather than applying additional filters, so
# router for restricted domain - this domain can only send or be sent

restricted_domain:
driver = accept
domains = restricted.doma.in
senders = *@restricted.doma.in
transport = local_restricted_delivery
# router for other domains
other_domains:
driver = accept
domains = doma1.in : doma2.in # but not restricted.doma.in
senders = ! *@restricted.doma.in
transport = local_normal_delivery
and use the same conditions on the general send-elsewhere router
Just wondering - any advantage to doing the restrictions in routers,
vs in the rcpt acl?
Two: Not necessarily germane in all cases:
1) Avoids the need for an acl_not_smtp clause, should there be on-box
sending accounts, some forms of webmail, or other webish critters.
2) Less likely to go awry, and easier to troubleshoot with fewer places
to look.
One downside:
More likely to give rise to an unwanted bounce, as it takes place
post-smtp session. One simple acl could prevent that.
Personally, I agree with Nigel's post - simplest and least chance of
entanglement with rules for other traffic if done in a separate Exim
instance with its own configure file.
